was wondering how to avoid getting killed when using Zeal, i noticed when you attack ,for instance, lighting enchanted enemies you cant move until the attack is over which can really suck if you have sucky equipment & resistances.

my question is can you interupt the attack yourself so you dont end up dying a million times over?

As has been said, you can't interrupt it. But, if you are attacking at 4frame speed, zeal shouldn't seem like any time out of your day. Though, if lightning enemies are really killing you, get positive resists and wear tgods for absorb, they'll heal you.

And conviction does work PvP, i'm not sure of the penalty though (if there even is one)
